Advantage of B imetal H ammerhead Hammerhead is a key component on the hammer crusher used in building materials, mining, chemical industry, etc. It is also a wearing part. The traditional hammerhead is mostly cast with high-manganese steel , and the high-manganese steel is used to improve the wear resistance under the impact load, but its wear resistance is far from being suitable for the modern production demand of high efficiency and low consumption. Due to the short life of the hammer and frequent replacement, the equipment operation rate is reduced. Therefore, it is necessary to seek a new material and new technology to improve the function and service life of the hammer. When the hammer head does not change its surface shape at the beginning of the work, the hammer head is mainly subjected to impact wear, and the material impacts the metal surface with a positive force to cause plastic deformation and impact craters. When the working surface of the hammer head is ground...

Characteristics and application of 9Cr18 stainless steel ball 9Cr18 stainless steel ball is a spherical iron-iron wear-resistant body which is mainly composed of carbon, chromium, manganese, molybdenum and the like, and is formed by forging, spinning, rolling, grinding and casting. It is crushed today. The most important part of the industrial and bearing industry. Steel balls are important basic components, especially precision industrial steel balls play a huge role in the development of the national economy. Under special conditions, steel balls of special materials are often required to perform the functions required in different environments. In fact, some special material steel balls have been widely used in various fields of the national economy, including stainless steel , copper , aluminum , titanium alloy steel and agate, glass, ceramic balls and so on. Their promotion and application not only promote the development of the steel ball production industry, but also promot...

Trader price "fear high" stepping down inventory: Since the beginning of this year, the price of iron ore has risen from 450 yuan per ton. At the beginning of July, it has hit a new high in the past five years, reaching a high point of 924 yuan per ton. But still linger near the high point. Then, the iron ore price has risen sharply within half a year, what impact will it have on domestic related companies? In addition to traders stepping up to inventory, steel companies are also stepping up shipments. The person in charge of a steel company in Hebei told the reporter that at present, the sales profit of downstream finished products has actually not kept up with the increase in raw material prices, but if it does not increase the strength of the warehouse, it is likely ...

Introduction and Application of Rubber Beams 1.       Introduction The rubber beam is vulcanized and bonded by a multi-layer rubber sheet and a thin steel plate. It has sufficient vertical steel to reliably transmit the reaction force of the upper structure to the abutment; it has good elasticity to adapt to the beam end. Rotation, and greater shear deformation ability to meet the horizontal displacement of the upper structure. In addition to the PTFE plate on the surface of the above-mentioned plate rubber bearing, it can be made into a PTFE sliding plate rubber bearing. In addition to vertical steel and elastic deformation, it can withstand vertical loads and adapt to beam end rotation. In addition, due to the low friction coefficient of the PTFE plate, the beam end can slide freely on the surface of the PTFE plate, and the horizontal displacement is not limited. It is especially suitable for bridges with medium and small loads and large displacem...
